Wolfspeed, Inc. is an American developer and producer of vast-bandgap semiconductors, focused on silicon carbide and gallium nitride materials and devices for energy and radio frequency functions such as transportation, energy supplies, power inverters, and wireless methods. Cree Research was founded in July 1987 in Durham, North Carolina. 5 of the six founders - Neal Hunter, Thomas Coleman, John Edmond, Eric Hunter, John Palmour, EcoLight bulbs and EcoLight bulbs Calvin Carter - are graduates of North Carolina State University. In 1983, the founders - one a research assistant professor and the others scholar researchers - had been looking for ways to leverage the properties of silicon carbide to enable semiconductors to function at larger working temperatures and power levels. In addition they knew silicon carbide might serve because the diode in light-emitting diode (LED) lighting, a light supply first demonstrated in 1907 with an electrically charged diode of silicon carbide. The analysis crew devised a option to develop silicon crystals in the laboratory, and in 1987 founded the company to supply silicon carbide for use commercially in each semiconductors and lighting.
In 1989, the company launched the primary blue LED, enabling the development of large, full-color video screens and billboards. In 1991, the company launched the first commercial silicon carbide wafer. In 1993, the company turned a public firm via an initial public offering. In 2011, the corporate acquired Ruud Lighting for $525 million. In August 2011, EcoLight LED bulbs the company introduced the XLamp XT-E Royal Blue LED to be used in distant phosphor lighting. In 2013, the company's first consumer merchandise, two family LED EcoLight bulbs, qualified for Energy Star ranking by the United States Environmental Protection Agency. In July 2016, Infineon Applied sciences agreed to amass the corporate's Wolfspeed RF and power electronics gadgets unit for $850 million. Nevertheless, the deal was terminated in February 2017 on account of regulators’ national security concerns. In March 2018, the company acquired the RF Energy Enterprise Infineon Technologies AG's for €345 million. In Might 2019, the corporate sold its Lighting Merchandise division (now branded as Cree Lighting) to Ideally suited Industries.
In September 2019, the company announced a $1 billion funding in a semiconductor manufacturing plant in Marcy, New York to build the world’s largest silicon carbide fabrication facility with a $500 million grant from New York State. In March 2021, the company bought its LED Enterprise to Sensible World Holdings for up to $300 million. In October 2021, the corporate changed its title to Wolfspeed. In April 2022, the Marcy, New York, facility opened. In November 2022, the company introduced that co-founder and Chief Expertise Officer John Palmour had died. In February 2023 it introduced it would construct its first European manufacturing unit in Germany. It is purported to be on the site of a former coal plant in Ensdorf, Saarland with ZF Friedrichshafen as a coinvestor and subsidized by the EU as an necessary venture of common European interest (IPCEI) for Microelectronics and Communication Technologies. In August 2023, it was announced the Lowell-headquartered semiconductor EcoLight dimmable firm, MACOM had entered into a definitive agreement to acquire Wolfspeed's RF business.
In June 2024, Wolfspeed has delayed its $three billion semiconductor plant in Germany to mid-2025, reflecting the EU's challenges in boosting native chip production. Wolfspeed announced the undertaking's indefinite hold in October 2024, citing low demand. As a result, ZF ceased to participate in the undertaking. In October 2024, the Biden Administration announced that it would provide Wolfspeed with up to $750 million in direct funding to assist the corporate's new silicon carbide manufacturing facility in North Carolina that makes the wafers used in superior computer chips and its manufacturing unit in Marcy, New York. On Could 20, 2025, it was reported that Wolfspeed was making ready to file for Chapter eleven bankruptcy within the approaching weeks after warning that it may be unable to proceed future operations after lower than anticipated annual sales were reported. Wolfspeed's inventory slid to barely over a dollar per share that day. On June 18, 2025, Wolfspeed introduced that they might promote itself to Apollo Global Management in a deal that would put the corporate right into a prepackaged Chapter 11 bankruptcy filing, which might permit for the elimination of nearly all of its multi-billion dollar debt.
Wolfspeed entered into a restructuring support settlement with its lenders and Renesas Electronics, and announced that they'd file for prepackaged Chapter eleven bankruptcy by July 1, as a part of a plan to remove $4.6 billion of debt, EcoLight home lighting stating they only had about $1.1 billion left in money. The corporate may also receive $275 million in financing backed by its lenders, with plans to finish restructuring by Q3 2025. After the announcement, Wolfspeed's inventory fell 30%, sliding beneath $1 per share. On June 26, 2025, EcoLight Wolfspeed started laying off workers from their manufacturing facility located in Racine, Wisconsin. On June 30, 2025, Wolfspeed filed for EcoLight Chapter eleven bankruptcy protection. On October 13, 2022, a amenities electrician was electrocuted at the Wolfspeed Research Triangle Park in Durham, North Carolina. The incident sparked a state investigation into his death in addition to public concern for the company's poor work security document. State Department of Labor investigations into the company have uncovered 17 office safety violations between 2012 and 2023, together with six serious violations.
